SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OpenAPI documentation and type-generation workflow that lets teams define, validate, and document APIs with a single source of truth.

Core Features & Use Cases

  • OpenAPI document authoring and generation for REST APIs.
  • TypeScript type generation and validation to ensure contract-consistency between server and client.
  • Code generation for clients and server stubs to accelerate integration and development.

Quick Start

Create an openapi.yaml document and run the provided tooling to generate TypeScript types and a client for your API.

FAQPage Schema
How do I generate TypeScript types from an OpenAPI specification?

You can generate TypeScript types from an OpenAPI specification by defining your API contract in an openapi.yaml file and running the provided toolchain to produce contract-consistent TypeScript types for your project.

What is the best way to maintain API documentation and client code consistency?

The best way to maintain API documentation and code consistency is using a contract-first OpenAPI workflow, defining a single source of truth that generates both API documentation and TypeScript client SDKs.

Can I use OpenAPI for contract-first API design in a TypeScript project?

Yes, you can use OpenAPI for contract-first API design in TypeScript projects by authoring an OpenAPI 3.1 specification to validate REST APIs and generate server stubs alongside client code.

How do I generate a client SDK from an OpenAPI YAML file?

To generate a client SDK from an OpenAPI YAML file, you create your openapi.yaml document and run the provided generation utilities to produce the client code required for API integration.

Do I need specific dependencies to run OpenAPI code generation?

Yes, OpenAPI code generation requires an OpenAPI toolchain including openapi-typescript and openapi-generator, an OpenAPI YAML or JSON spec, and a TypeScript project to consume the generated types and clients.

Why use a single OpenAPI specification for REST API development?

Using a single OpenAPI specification for REST API development lets teams define, validate, and document APIs with a single source of truth, preventing contract drift between server and client implementations.
